The communication industry opened 5G-A in the new stage of multi-countries to step up the deployment of 6G research and development

21st Century Economic Herald reporter reported to Harbin to report

At this year's "2022 World 5G Conference", 6G's forward -looking research has become a hot point. This is not only the core area of ​​future digital innovation and development, but also has become one of the main battlefields of the game.

"When the commercial use of each generation of mobile communication is the time of the new generation of mobile communication." Said He Heye, an academician of the Chinese Academy of Engineering, said that at the current stage of 6G's early vision research stage, relevant global organizations are actively discussing the vision needs of 6G and carried out key key. Research on technology. In the future, 6G will fully support the digital transformation of the whole society and realize the physical world and the digital world.

At present, many countries and manufacturers have begun 6G technology pre -research at the same place and run 6G. The "6G Communication Technology Patent Development Report" released by the State Intellectual Property Office shows that China's patent applications in the field of 6G communication technology in the world accounted for more than 30 %, ranking first in the world.

5g-a to 6G step by step gradual

Today, 5G has begun commercial use, 5G technology is still moving forward. The last version of the first stage of the 5G standard-R17 standard frozen, which also means that the 3GPP (the third-generation partner plan is an international standardized organization) for the 5G-Advanced standard formulation work will be fully launched. 5G-Advanced will define new goals and new capabilities for 5G subsequent development. Through network evolution and technology enhancement, 5G can generate greater social and economic value.

In the future, Zhang Xinsheng, Executive Vice Chairman of the Mobile Communication Forum, told the 21st Century Business Herald that 5G-Advanced is a must-have stage for 5G development. 5G-Advanced greatly improves 5G network performance and enriches 5G application scenarios. It is unrealistic. 5G-Advanced has consolidated the foundation for the greater value of 5G in the digital economy era.

Fang Hanting, a professor at the coordinated development research center of Zhejiang University, reminded that the current 5G enhanced technical standards are still evolving, and support measures to achieve innovation leaders need to be further strengthened. The complete 5G R15 and R16 standards are not enough to fully meet the needs of the vertical industry. In terms of the formulation of international standards, equipment research and development, and verification of 5G subsequent versions such as R17. Essence

"Generally speaking, the development cycle of each generation of mobile communication technology is about 10 years, so before 6G arrives, there is still a long time to promote 5G to continue to develop. Many of the technologies we study today are likely to be very likely that it will be. Become one of the 6G technology help, "said Xu Hao, the person in charge of the research and development of Qualcomm China.

Xu Hao pointed out that in fact, not every technology will be introduced in accordance with the 10 -year cycle. If you want to introduce artificial intelligence (AI) technology in the next generation of wireless communication, you need to take the lead in planning and research in 5G or 5G Advanced in 5G or 5G Advanced In the future, further promotion and application can be obtained in the 6G standard.

So, what changes will 6G bring to social production and life in the future?

Wang Jun, vice president of Huawei Wireless Network Product Line and chief scientist of 6G, pointed out that 6G is not only an upgrade of capabilities, but also develops two key scenarios of intelligence and perception on the basis of 5G. 6G will become a key factor in the popularization of artificial intelligence, bringing intelligence to everyone, every family, each car, and each enterprise.

Specifically, 6G will have six typical application scenarios, including: distributed network machine learning and interconnection AI, perception, positioning and imaging, people -centered immersive communication, smart city and smart life, full functional industry 4.0 and its itself Evolution and mobile services global coverage.

Chen Shanzhi, deputy general manager of China Xinke Group, director of the expert committee, and director of the National Key Laboratory of Wireless Mobile Communications, pointed out that, compared to 5G, 6G needs to further solve the problem of wide area coverage and local coverage. Wide -area coverage needs to rely on star -land fusion mobile communication implementation, while local coverage should support the virtual world and immersive meta -universe experience with high bandwidth and communication capacity. It is a huge change brought by 6G.

Multi -country layout 6G in advance

However, 6G's research and development also faces some challenges.

当前 调 调 emphasized that the current accurate prediction of the difficulty of mobile communication from 2030-2040 is no less than the discussion of new technologies. "The higher the demand is, the better, it is not just serving the niche market. Without the public that the public cannot support 6G, 6G can lead the upstream and downstream development of the industry chain, but too advanced out of the industry ecology may lead to heroes useless."

Zhang Ping, an academician of the Chinese Academy of Engineering, pointed out that the four blocks of 6G in the process of evolution, one is the lack of leading basic theory; the other is that the necessary support links are weak; the third is that the "killer" application platform is still lacking; the fourth is that the open source ecosystem has not yet yetn not yet yet. Complete, we need to strictly prevent future mobile communication forming a newborn block.

Regarding how to open these blocks, Zhang Ping believes that it is necessary to use Zhijian as the core concept of the mobile communication system, short -term relieving high -end chip "card neck" problems, and long -term theoretical original innovation and new model ecological construction. Continuous development.

Although the industry generally predicts that 6G commercial use will not be achieved until around 2030, many countries and manufacturers have begun 6G technology pre -research at the same place and run 6G. From a domestic point of view, domestic universities and scientific research institutions account for the top ten of China's patent application rankings, and the basic research and development of 6G communication technology is the main force of 6G communication technology innovation.

In contrast, Japan, South Korea, and the United States are more active in science and technology companies. Japan NEC, South Korea Daewoo Communication Company, Mitsubishi Electronics Company, South Korea Telecom Research Institute, South Korea Samsung Electronics, American Shusi Network System Company, Japan Foreign companies such as NTT Corporation, Qualcomm Corporation of the United States, and US Health Corporation ranks among the top ten global patent applications.

Zhang Ping suggested to implement the "government + market" two -wheel drive model, and build a core technology innovation consortium led by the government, market -oriented, and win -win multi -party mobile communications to achieve a series of blocks such as basic research, major technology, and innovation applications. Cooperation breakthrough. At the same time, establish a wide open science and technology alliance and reshape the international environment that breaks through the block. The forward -looking layout of 6G technology research and development, spectrum planning, standard development, etc., forms multi -level core capabilities such as core patents and system performance. Strengthen multilateral cooperation and win -win mechanisms, and build a new "competition" relationship with technical strength and international influence.

Wu Hexuan said that the current study of 6G and 5G ten years ago were more severe than the situation, but at present, we still have to adhere to the standardization of 6G. Based on the concept of open cooperation, we must carry out international cooperation between 6G technology and future industries with greater energy.

Regarding the specific time point of 6G standardization, Chen Shanzhi said that 6G is still in the cutting -edge technology research stage, and the standardization process is expected to begin in 2025, and the standard fixation will be achieved in 2030.

Wang Jun believes that the global unified standard is still the only way for the development of 6G in the future, and it is also the direction of the entire industry. At present, with the cooperation and efforts of various industrial partners in the world, next year's ITU research working group will release 6G vision, to achieve a 6G research vision consensus worldwide, and in the next 3-4 years Research and verification, and do relevant preparations.
